Display blocks of text in UI received from MQTT or from executed pyhon script

Is there somewhere a proper “button” card that is available and if not, is there a way to use the “string” card to actually publish the MQTT message ?

See

mainUI Pages (Layout) question

The components of the System Widget Library are the individual components with which you can build your own custom widgets so you can’t just put an oh-button on a page. There is not Button Card because this doesn’t really make sense (it doesn’t add any additional functionality) given that the cards themselves, via their action configuration, can be configured to have all of the same action effects as a button.

get it to actually publish the MQTT message

From UI, you can send an arbitrary string to an Item as command.
What happens to it then depends on what bindings or rules it is linked with.

If you are looking to have your string embed details from other Items or calculations etc., it’s almost certainly better to process that in a rule rather than trying to build complex strings in the UI widget.
